A

situation especially designed fo observing behavior

17
Q

internal reliability =

A

are items consistent with eachother?

18
Q

inter-rater reliability =

A

are coders consistend with each other?

19
Q

cronbachs alpha =

A

it helps researchers determine how well a set of questions work together and provide consistent results. A higher alpha value indicates stronger reliability, while a lower value suggests a need for improvement or further evaluation of the questions being used.
–> If Cronbach’s alpha is 0.7 or higher, it means the questions in the survey are working well together and measuring the same concept reliably.
–>If Cronbach’s alpha is below 0.7, it suggests there might be some issues with the questions, and they may not be consistently measuring the concept.

20
Q

cohen’s kappa =

A

it helps us understand how much they agree with each other beyond what we would expect by chance.
In general terms, if the kappa value is above 0.6, it indicates substantial agreement between the raters. If it’s below 0.4, it suggests poor agreement.
